Embodiment Construction

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] Such as figure 1 and figure 2 As shown, the present invention comprises workbench 2, and described workbench 2 is provided with arched boss 3, and above described boss 3 is also provided with elevating device, and the lower surface of described elevating device is connected with pressing device, heating device and cooling device.

[0028] After the horn 1 is positioned on the boss 3 on the workbench 2, adjust the lifting device so that the pressing device presses the horn 1 tightly to prevent it from moving. The foam 9 is also provided with a gasket 7 passing through the dry plastic rod 5 above the foam 9, and the plastic rod 5 is heated by a heating device to melt and attach to the surface of the gasket 7 to prevent the foam 9 from moving. Then it is cooled by cooling device.

[0029] The lifting device includes a connecting plate 4 that can move...

Abstract

The invention discloses a hot melting device for fixing foam. The hot melting device comprises a workbench, wherein a vaulted boss is arranged on the workbench; a lifting device is arranged above the boss; and the lower surface of the lifting device is connected with a hold-down device, a heating device and a cooling device. A loudspeaker is arranged and located on the boss on the surface of the workbench, the lifting device is regulated so that the hold-down device pushes tightly against the loudspeaker and prevents the loudspeaker from moving, a plastic rod fixed with a loudspeaker casing and the foam penetrating through the plastic rod are arranged on the surface of the loudspeaker, a gasket penetrating through the plastic rod is arranged above the foam, and the plastic rod is heated by the heating device, melt and attached on the surface of the gasket to prevent the foam from moving, and cooled by the cooling device.

Description

technical field [0001] The invention relates to a device for attaching foam to the outer wall of the horn during the horn processing process. Background technique [0002] In order to reduce the vibration of the horn shell and the air leakage of the textile horn shell, it is usually necessary to attach the foam to the outer wall of the horn with an adhesive such as glue. In this way of attachment, the foam is easy to fall off during use, and the adhesive itself has A certain thickness will affect the sound insulation effect. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device for attaching foam that is firmer and has better sound insulation effect. [0004] In order to solve the above problems, the present invention provides a foam fixing hot-melt device, which includes a workbench, an arched boss is arranged on the workbench, and a lifting device is arranged above the boss, and the lifting The lower surfa...
